P2A00 - A/F Sensor Circuit Range/Performance (bank 1 sensor 1)

Nismodean

I've been having this issue for quite some time, bank 1 sensor 1 P2A00 code with random misfire (reset it multiple times and it comes back) and the RPM dip when I come to a stop. So either I pay $700 for two wideband o2 sensors and hope that clears the code issues or pay ~$600 for an uprev tune that also removes that code detection along with a mild tune for FI LTH and exhaust?
